Description

The invention relates to a basic anchor, which is directly insertable into a floor, comprising an at least partially hollow main body, wherein in this at least two movable, can be driven into the ground arms are arranged.

Furthermore, the invention relates to a use of such a basic anchor.

Basic anchors are known from the prior art. These are used in particular for the attachment of tents or the like, wherein these are driven into a ground. In a simple embodiment, ground anchors are rod-shaped with a hook at their upper ends. About the hook a rope or the like with the ground anchor on the ground can be fastened.

Such simple trained ground anchors or pegs have the disadvantage that they are not designed to be particularly stable or stabilizing. Therefore, with such pegs no large loads fastened, as they can solve even at low forces from the soil or soil.

To overcome this drawback, more complex ground anchors have become known. In the DE 1 942 775 A For example, an anchor comprising a pile with a tip end is disclosed. Furthermore, this tenting arms are provided which are slidably disposed within the pile. These tentacles come out of the ground when a force is exerted. However, it is disadvantageous that the tentacles form a hook in the ground, so that they can not be moved back into the pile.

In the US 1,629,353 A there is disclosed a ground anchor which, after insertion thereof into a ground, can be worked so that arms exit into the earth. Furthermore, such a basic anchor also includes means for retracting the arms. However, a basic anchor disclosed in this document has the disadvantage that it must be inserted into a hole to be made in the ground and constitutes a permanent fixture.

The object of the invention is to provide a basic anchor of the type mentioned, with which tents or the like are stably fixed and which is used several times.

Further, it is an object of the invention to provide a use of such a basic anchor.

The object is achieved in that in a basic anchor of the type mentioned, the arms for fixing the ground anchor in the bottom are reversibly moved out of the main body, wherein the arms are formed elastically deformable.

An advantage achieved by the invention is to be seen in particular in that, as a result of the elastically deformable or flexible design of the arms, they can be introduced into a soil or into a soil in such a way that the basic anchor is fixed in the soil in the soil in a detachable manner. When driving the arms, these are bent at the same time, so that a good anchoring is achieved with little effort. For this purpose, it can be provided with advantage that the arms are already arranged with a slight or slight bend in the main body. The elastically deformable formation of the arms in combination with the immediate insertion of the ground anchor in the ground allows a repeated use of the same, this is easy to handle. A previous creation of a hole in the ground for later attachment of the anchor is not required.

The basic anchor or its main body is in particular formed rod-shaped with a round cross-section. However, the cross section of the main body can also be formed, for example, oval or polygonal. In order to enable a simple insertion of the ground anchor in the ground, it is advantageous if this is rotationally symmetrical.

A number of arranged in the main body movable arms is particularly dependent on how strong an attachment should be and what maximum force for driving should not be exceeded. Also, the diameter of the main body plays a role in this regard, as far as a simple production is concerned. in principle applies, the stronger the attachment should be or the larger the diameter, the more arms can be arranged in the main body.

In order to introduce the basic anchor directly or directly and without a previously created hole in the ground or in a soil, for example, by hammer blows, a lower end of the basic anchor may be formed tapered. The lower end of the basic anchor is that which enters as the first part of the same in the ground. Furthermore, it can also be provided that the arms themselves are formed at an exiting into the ground end with a taper, so that an introduction of the same is facilitated in the soil. A cross section of the arms can in principle be of any desired design, for example round, oval, rectangular or square. These are preferably flat in each case. The basic anchor is expediently made to a large extent of a steel, so that it is robust and resistant and thus designed for repeated use.

It is advantageous if the main body is formed with a tip end, wherein the arms are moved out of the main body above the top. The tip is preferably conical or cone-shaped. However, it may be provided that the conical shape is interrupted circumferentially or the cone is not executed over the entire surface. The end-side design of the main body with a tip allows a simple, as possible resistance-free insertion of the ground anchor in the soil or the soil. The tip is arranged at this end of the main body, which first enters the ground. Penetration of the ground anchor in the ground is preferably carried out by hammer blows on the tip of the opposite end of the main body. This can for this purpose include a closure element, which z. B. is arranged non-positively releasably connected to an upper end of the main body. In order to move the arms above the tip out of the main body, recesses are provided therein, a number of the recesses corresponding to a number of the arms. The recesses are designed so that the arms pass through them with as little play as possible in order to prevent soil from entering the hollow main body. At the same time, however, the recesses are formed with the play so that the arms can escape through the same as possible without resistance. Furthermore, it is advantageous if the tip within the main body with a conical Form is formed so that the arms when exiting the main body rest on such a cone.

It is advantageous if, within the main body, a detachably locatable actuating bolt for driving the arms is provided. In particular, the actuating bolt is insertable into the main body after insertion of the basic anchor into the ground. The arrangement of the actuating bolt in the main body is advantageously non-positively, for example by a screw or a bayonet lock. After mounting, the actuating pin projects out of the main body.

It is provided that the actuating pin interacts directly or indirectly with the arms in order to move the arms partially out of the main body by exerting force on the actuating bolt. Preferably, in this case, the actuating pin interacts indirectly with the arms via a connecting element, via which when force is applied to the actuating bolt by, for example, hammering, this force is transmitted to the arms, whereby they move out of the main body. The arms are preferably arranged non-positively on a lower end of the connecting element, wherein the connecting element is slidably mounted or movable in the main body. At an upper end of the connecting element this takes the actuating pin force and / or positively releasable, for example via a screw or a bayonet lock. In order to actuate the actuating bolt in a ground anchor located in the ground or ground, this can be formed with a greater length than the main body. Conveniently, the length of the actuating bolt is adjusted relative to the length of the main body so that the actuating bolt still protrudes from the main body when the arms are fixed in a driven-in position in the ground. As a result, the arms can later easily be released from the ground again by counteracting actuation of the fastening bolt and brought into the original position. The actuating bolt is preferably operated with hammer blows on the upper end or set in motion.

Alternatively, an extension direction of the arms may be changed to use the ground anchor in the soft or loose soil, so that a spread not only in Forward direction, but also in the reverse direction or upwards can take place. In this case, the arms can be pulled out of the main body by means of a slide hammer.

Conveniently, a partially disposed within the main body fastener is provided for a rope, wherein the fastener is releasably connectable to the main body. The fastener is insertable into the same after removal of the actuating bolt from the main body. For this it may be necessary to remove the end element first. This in turn is preferably non-positively connected to the main body, for example via a screw connection. Also, the fastening element preferably projects out of the main body of the basic anchor and its upper end is formed so that a cable or the like can be fastened thereto. For this purpose, this can be formed for example with a hook or a ring.

It is advantageous if the fastening element comprises a cover, on the one hand to protect the basic anchor or its components against damage and on the other hand to prevent leg injuries in the event of unintentional contact. The cover is preferably formed from a plastic.

It is advantageous if a returnable element which can be fastened detachably within the main body is provided for retrieving the arms from the floor. The return element is designed, for example, as a slide hammer and can be inserted and detachably fastened in the hollow main body of the basic anchor. It is understood that for this purpose both the fastener and the actuating pin are removed from the main body. Also, the return member preferably protrudes from the main body and is formed at an upper end so that it can be operated by hammer blows on the same so that the arms are recoverable back into the main body. At the same time or in a second step, the entire ground anchor can be removed from the ground again by actuating the return element. Optionally, the actuating bolt may be formed so that it can also serve as a return element. In this case, a part is unnecessary, which simplifies the overall construction.

It is advantageous if the arms are formed from a spring steel. Spring steel has the advantage that it is elastically deformable in the given dimensions of the arms or is formed flexible. In addition, this additionally has a higher strength compared to other steels.

A use of a basic anchor according to the invention is advantageously carried out for the attachment of tents.
